Title: Polymers containing disulphonimide groupings and a process for the production thereof
IPC: C08F220/46
Filed: 1960-02-18
Abstract: Olefinically unsaturated disulphonimides containing at least one disulphonimide group and also at least one olefinically unsaturated double bond are polymerized either alone or in admixture with one or more other vinyl compounds.  Specified disulphonimides are vinyl phenyl and vinyl methyl disulphonimides, vinyl-benzene-benzene-disulphonimide vinyl benzene-methyl-disulphonimide, methacrylamino-benzene-benzene disulphonimide, methacrylaminobenzene-methyl disulphonimide, and the reaction product of [b -isocyanatoethyl]-methacrylate with p-amino benzene benzene-disulphonimide.  The olepolymerization may take place by block solution dispersion or emulsion method using peroxides such as hydrogen peroxide persulphates, alkyl and aryl peroxides, acyl peroxides, hydroperoxides azodiisobutyronitrile and using if required Redox systems.  Known emulsifiers may be used in emulsion polymerization.  Specified vinyl compounds are acrylonitrile, methacrylonitrile, acrylic and methacrylic acids, esters and amides, styrene, divinyl benzene, vinyl chloride, vinyl esters, vinyl sulphonic acid, butadiene, isoprene, chloroprene, 1, 1-dichloroethane and maleic and fumaric acids.  Terpolymers may be used-specified are acrylonitrile, methyl acrylate and vinyl benzene-benzene-disulphonimide; acrylontrile, methacryl-amino-benzene-benzene sulphonimide and vinyl benzene-methyl disulphonimide; and butadiene, acrylonitrile and reaction products of [b -isocyanatoethyl-] methacrylate and aminobenzene-benzene disulphonimide.ALSO:Olefinically unsaturated disulphonimides containing at least one disulphonimide group and also at least one olefinically unsaturated double bond are prepared in known manner by reacting styrene sulphonamide with benzene and/or methane sulphonic acid chlorides in an alkaline medium, or by the reaction of unsaturated acid halides or acid anhydrides such as acrylic, methacrylic or crotonic acid chlorides and maleic anhydride with disulphonimides containing acylatable groups e.g., primary or secondary amine groups or hydroxy groups, or by the reaction of unsaturated isocyanates such as [b -isocyanatoethyl]-methacrylate with hydroxy or amino-disulphonimides.  Thus methacrylamino-benzene-benzene disulphonimide is obtained by reacting aminobenzene-disulphonimide with methacrylic chloride in aqueous solution in the presence of soda, followed by acidification with hydrochloric acid.  Also vinyl benzene-benzene-disulphonimide is obtained by reacting styrene sulphonamide with benzene-sulphonic acid chloride in alkaline solution and acidifying with hydrochloric acid. Finally a disulphonimide is prepared by reacting [b -isocyanatoethyl]-methacrylate with b -aminobenzene-benzene-disulphonimide and has the formula: <FORM:0867006/IV (b)/1>

Title: Improvements relating to ironing-machines
IPC: D06F67/00
Filed: 1936-02-26
Abstract: 459,753. Ironing-machines. ELECTRIC HOUSEHOLD UTILITIES CORPORATION, South 54th Avenue, Chicago, U.S.A. Feb. 26, 1936, No. 5821. Convention date, July 19, 1935. [Class 138 (ii)] [See also Group XIV] The table 5 to which the support 6 for the moving roller 7 and shoe 8, the motor 10 and gear-box 11 are rigidly secured is arranged to be housed, when the ironer is not required, in a vertical position within a cabinet A, and to be drawn therefrom to the horizontal operative position. Rollers 13 carried by the table traverse curved guides 14 within the cabinet and the lower ends 18a of cranked links 18, of which the other ends are pivoted to the underside of the table, traverse vertical guides 17. Other links 25, pivoted at 26 to the cranked links, swing about fixed pivots 27. As the table is drawn out of the cabinet the portion 31 of a leg C is automatically swung from a position wherein it is approximately parallel to the table into a supporting position by means of a spring arranged around the pivot 35 of the two leg parts 30, 31 and the two parts are latched together by a spring pressed plunger 44 engaging a recess 43 in the upper end of the part 31. As the table is being pushed from the operative position into the cabinet the movement of the links 18 operates a spring pressed plunger 46 to withdraw the plunger 44 and unlatch the leg parts. During further inward movement of the table the part 31 is engaged by a swinging bail 52 pivoted at 53 whereby it is rotated clockwise relatively to the part 30 against the force of the spring around the pivot 35 into the folded position. A stop 42a prevents opening movement of the part 31 beyond the straight line position. If the leg meets an obstruction during opening movement whereby it cannot automatically assmne its full straight line position the parts 30, 31 are temporarily locked by the engagement of the plunger 44 in another notch 55 so that the apparatus will not collapse when released by the operator. In a modification the part 31 of the leg is positively moved into straight-line supporting position by means of a cam and lever mechanism operated by the swinging of the links 18, and is moved by a spring into its folded position. In a further modification the leg is positively operated in both directions by rack-and-pinion mechanism operated by the movement of the links 18.

Filed: 1963-02-13
Abstract: 956,121. Counting apparatus. K. KÍRBER. Feb. 13,1963, No. 5826/63.Heading G4D. The drive to a cigarette-making machine is maintained only as long as the rate of production exceeds a predetermined figure. To start the machine an operator moves slider 41 to the left so that current from a source E through clutchoperating relay 32 increases progressively. The cigarettes C are detected photo-electrically so that amplifier 7 produces pulses on.leads 8, 9, 33. A total count is registered at 10. When the rate exceeds 500/minute relay 11 closes contact 12 while contact 44 simultaneously opens, clutch relay 32 being now dependent on relay 11. If the rate falls below this value contact 12 opens, the machine stops, and slider 41 returns to home position. If the rate exceeds 1000/minute relay 34 closes contacts 35 to operate a device B. A batch counter operating to every tenth, twentieth or hundredth pulse from amplifier 7, Fig. 2, operates relay 16 at a predetermined count to operate a device D. Similarly, rate meter 22, Fig. 3, operates a device A at a predetermined rate.

Filed: 1967-02-08
Abstract: 1,170,631. Isolating switches. BOWTHORPE LINE EQUIPMENT Ltd. 8 Feb., 1967, No. 6124/67. Heading H1N. In an isolating switch of the kind having an elongated contact blade D carried by an insulator B<SP>1</SP> which is rotatable to swing the blade so that an operative portion ofthe blade is moved between opposed contacts carried by a fixed insulator, the blade then being turned about its longitudinal axis to establish adequate contact pressure, premature turning of the contact blade is prevented by locking means which are only released when the operative portion of the blade has been swung between the opposed contacts. As shown these locking means comprise a toggle linkage J ... J<SP>8</SP> interconnected between the rotatable insulator B<SP>1</SP> and the contact blade D. When the switch is open, the toggle formed by links J<SP>2</SP>, J<SP>3</SP> is held overset against a stop G<SP>3</SP> by a spring K. Thus when the insulator B<SP>1</SP> is turned to close the switch, the linkage turns the blade holder G and the contact blade D without the contact blade D turning on its axis within the blade holder G. When the operative end of the contact blade enters the opposed contacts a part carried by the blade co-operates with a fixed abutment so that an initial turning movement about its axis is imparted to the blade. This initial movement causes the toggle J<SP>2</SP>, J<SP>3</SP> to collapse so that as movement of the insulator proceeds, the blade is turned on its axis by the toggle linkage, the link J<SP>3</SP> moving in a slot G<SP>1</SP> in the blade holder G. A toggle formed by the links J<SP>1</SP>, J<SP>2</SP>is overset when the switch is fully closed.

Abstract: 371,038. Cellulose. DREYFUS, H., 22, Hanover Square, London. Nov. 11, 1930, No. 6307/32. Divided on 371,001. [Class 96.] In a process for producing cellulose or cellulosic materials by treating wood, straw, grass or the like with hot acid liquors under pressure, the treatment is effected in the presence of one or more volatile aliphatic alcohols, which exert a pressure in the digester. Additional pressure may be produced by other means, e.g. by pumping inert gases or vapours into the digester, or by their development from materials introduced into the digester for that purpose. The pressures employed are higher than usual, e.g. 20-100 atmospheres, and the temperature is preferably 100-120‹ C. In an example wood chips are subjected to vacuum and impregnated with 10-20 times their weight of a sulphite cooking liquor containing 3-4 per cent total SO2 of which about 1-8-2-8 per cent is free and about 1-2 per cent is combined. 10-35 per cent of the weight of the wood in ethyl or methyl alcohol is added, the digester closed, and nitrogen pumped in until the pressure is 15- 25 atmospheres. After 1-2 hours the temperature is raised to 110-120‹ C. and maintained at that temperature for 16-24 hours.
